I thought that this rule was clear but we started arguing with a friend of mine about this rule, so I'm want to ask here to get full response, similar issue was already discussed on BGG however I was not fully satisfied about it.

Are bonus CP ALWAYS added to the base CP allowance number?

The point of discussion was that starting from scenario number 5 there is a sentence:

From now on, only icons will be provided for starting MPO and base CP allowance. Refer to previous scenarios if needed for explanatory text.

So the issues is

Friend of mine thinks that when the bonus CP addition is not explicitly declared in the scenario description, they are no accounted during the whole scenario (thus effectively bonus CP rule would be taken in action in first few scenarios and then in S.A.G.S

In my opinion the approach is same as in the previous scenarios, where they had this just as a reminder
